Products Application

Laboratory
Diammonium hydrogen phosphate can be used in the laboratory to prepare buffers and media, and it serves as a nutrient for yeast cultivation. It can also be used as an analytical reagent for the precipitation of magnesium, zinc, nickel, uranium, etc., and as a pH buffer. In electrochemical analysis, it can be used as a supporting electrolyte.
Food Industry
Diammonium hydrogen phosphate is used in the food industry as a food leavening agent, dough regulator, buffer, yeast food, bread improver and fermentation aid for brewing, and it can also be used for refined sugar.
Agriculture
Diammonium Phosphate is a compound fertilizer containing both nitrogen and phosphorus nutrients. It is a high-concentration, quick-release fertilizer. After dissolution, it has less solid matter. It is suitable for various crops and soils, especially for crops that require both nitrogen and phosphorus. It can be used as both base fertilizer and topdressing. When applied to acidic soil, it can reduce the fixation of iron and aluminum on phosphorus, maintaining higher phosphorus activity. It should be applied deeply. In animal husbandry, it can be used as a feed additive for ruminants.
Chemical production
Diammonium Phosphate is used for flame retardant treatment of fabrics, paper, wood, and plant fibers, as well as for impregnating wicks to increase their durability and self-extinguishing properties after matches are lit. It can be used as a dry powder fire extinguishing agent and phosphorus in fluorescent lamps. It can be used as a welding flux for tin, copper, bronze, and zinc. It is also used in the fields of printing plate making, vacuum tube manufacturing, ceramics and enamel industries. In the dyeing industry, it is used for chrome dyeing of wool fabrics.
Water treatment
Diammonium hydrogen phosphate is mainly used as a corrosion inhibitor in the water treatment field, as well as a nutrient for bacteria in the biochemical treatment of wastewater, and is also used as a softening agent component for boiler water.
